Implement a Timer in a Method

Question

I am doing a project in Java (RPG-Game) and there is a method, called "sleep()", if the hero sleep he can't fight against enemys or others and if he has for example 1 HP after he slept he gets max HP and then he is ready to fight. And my problem is that I need a timer for the sleep method, for example the Hero "Venus" sleeps for 3 Minutes and he can't fight in that time.

My attributes and my method:

public class Superhero {
private String id = UUID.randomUUID().toString();;
private String name;
private int healthPointsMax;
private int healthPointsCurrent;
private int damage;
private int critStrike;
private int critChance;
private String heroRole;
private int experiencePoints;
private String superpowers;
private boolean readyToFight;
private boolean inFight;
private boolean alive;`

and my method:

public void sleep() {
    System.out.println("Dein Superheld " + name + " legt sich schlafen.");
    System.out.println(name + " hat wieder volle HP, wenn er/sie wach ist.");
    setHealthPointsCurrent(getHealthPointsMax());
    readyToFight = false;
}

Did you try anything yet as for the timer? I don't see anything related to that in your post. — D. Lawrence

maybe you ask your question also on gamedev.stackexchange.com — Martin Frank

Do you want nothing else happen while the hero is sleeping or do you want the rest of the game to continue (with the restriction that they can't fight)? — Joachim Sauer

you can try using a java.util.Timer in your method as below :

public void sleep() {
    System.out.println("Dein Superheld " + name + " legt sich schlafen.");
    System.out.println(name + " hat wieder volle HP, wenn er/sie wach ist.");
    readyToFight = false;
    Timer timer = new Timer();
    TimerTask task = new TimerTask() {
         public void run() {
              setHealthPointsCurrent(getHealthPointsMax());
              readyToFight = true;
              timer.cancel();
         }
    };

    long delay = 120000L; // 2 minutes delay
    timer.schedule(task, delay);
}

Okay, Thanks I understand and if I write to long delay = 1000 would be that than 1 second? :/

You can instanciate an actual Timer in Java. Check the documentation here: https://docs.oracle.com/javase/7/docs/api/java/util/Timer.html
